Configuration.—The Gorilla is the largest, strongest and most formidable of the Primates. The adult male may attain the length of 6 ft. from the crown to the heels, but the female is smaller, her length rarely exceeding 4J ft. The arms and chest are of great size, but the legs are insignificant in comparison. The hands reach below the knees when the animal is erect, and the span of the outstretched arms exceeds the length of the body.
The relative proportions of the segments of the arm are more like those in Man than are those of the other Apes. Thus the arm is longer than the forearm, whereas the reverse is the case in the Gibbons, Orang
